I downloaded the 64 bit version of mint maya and loaded it on a 8GB pendrive through ubuntu using startup disk creator. And then when i try to boot into the live desktop environment this is the error that is produced.

Write down on a piece of paper the commands in the code blocks above. After clicking "OK" on the error dialog, you should be in the console with sudo priviledges. Start typing the commands, one at at time, in the console.

I had this exact same issue. I had used the Universal USB Installer to put Mint onto a 16 gig usb drive. The problem turned out to be that I didn't allocate any persistent storage on the USB drive. I redid the drive adding 500 mb persistent storage and everything worked like a charm.
